that the configuration of the worker in the FPGA builder is problematic, and the hardware won't be successful. Step 2:Change the specified function to hardwareNow we want to use the hardware interface line of the sum_elements () function. The following example selects accelerate with the nio ii c2h compiler for sum_elements. After the selection, there will be more c2h settings below. Select "build software and generate system" and "use hardware

From FPGA/CPLD Application Design Example 1 Use lowercase letters for all signal names, variable names, and port names, and uppercase letters for constant names and user-defined types. Use meaningful signal name, variable name, Port name, and parameter name. The signal name length should not be too long, and strive to be concise and clear. Use CLK as the prefix of the signal name or signal name for the clock signal (when multiple clocks e

1 Decision Tree The IF else statement and case are used in FPGA. A) if else is privileged, similar to priority encoding (when the two conditions are both true, only the first condition is true). Therefore, the IF else structure should be used when there are privileged conditions, the privileged order of parallel if condition statements is exactly the same as that of if else. B) case statements are often (not always) used in conditions where all con

Traffic, latency, and time series traffic in FPGA design: The data bit that can be transmitted in each clock cycle. Time delay: the clock period that data goes through from input to output. time sequence: The maximum latency between two components. It determines the maximum clock speed of the system. 1 pipeline can increase the traffic, for example, computing x ^ 3, Iterative StructurePipeline: Traffic = 8/1 latency = 3 Time Series = multiplier latenc

[Serialization] FPGA OpenGL series instances Registers of Tilde I. Principles Registers are used for storage by computers and other digital systems.CodeOr the logical part of the data. Its main component is the trigger. A trigger can store one binary code. Therefore, the register for storing n binary code requires n triggers.The functions of registers and data latches are the same. The difference is that the latches are level signal control and

[Serialization] FPGA OpenGL series instances Data Selector Based on OpenGL I. Principles Data selection refers to transferring data from multiple channels to the unique public data channel after selection. The logical circuit that enables data selection is called a data selector. It acts as a single-knife, multi-Throw Switch with multiple inputs. Table 1.1 select a data selector truth table II. Implementation In the design file, enterCo

[Serialization] FPGA OpenGL series instances 3-8 Decoder Based on OpenGL I. Principle: Decoding is the inverse process of encoding. Its function is to identify binary codes with specific meanings and convert them into control signals. A logic circuit with decoding function becomes a decoder.The decoder can be divided into two types:CodeConvert to one of the valid signals. This decoder can be called a unique address decoder. It is often used for

It is a hardware description language used for digital system design. It can be used for logic design at various levels, as well as simulation and verification of digital logic systems, timing analysis, and logic synthesis. At present, OpenGL is the most widely used hardware description language. The highest level of learning hardware is to have a circuit in our hearts. For those who are new to FPGA and HDL, the most important thing is to have more

Sends the output of the divider to the triggerCEDetection when the system clock arrivesCESignal validity whenCEWhen the signal is valid, the trigger output is changed, which is exactly the same as that of the divider, and this processing also makes the wiring more optimized. For multi-fan-out problems, it usually refers to the use of one node to drive multiple lower-level logical devices. For triggers with a
